IMPROVEMENT lN AGRICULTURAL BOILERS.

Specification forming part of Letters Patent No. 145,517, dated December 16, 1873; application filed November 6, 1873.

To all whom it may concern Be it known that I, HORACE A. MEARS, of

I Rockford, inthe county ofVVinnebago and in the State of Illinois, have invented certain new and useful Improvements in Agricultural Boilers;

and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of an agricultural boiler, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a longitudinal vertical section of my boiler through the line a: w of Fig. 3. Fig. 2 is a perspectix e view of the plate upon which the fuel is placed, with the lower ends of the draft-pipes. Fig. 3 is a horizontal section through the line 3 y, Fig. l.

A represents a tubular cylinder, of any suitable dimensions, provided with a stationary bottom, B, and a removable cover, 0, forming the fire-box or heater. D represents the flue for lettingin air to the fire, said flue being suspended from the upper edge of the heater by a hook, a, and its lower end held by an arm or projection, b, from the plate E, upon which the fuel is placed. G represents the outlet-pipe for the smoke. Both of these pipes or flues, I) and G, are made separate from the heater, and cannot warp so as to detach from the sides. When these flues burn out they can easily be removed at little trouble and expense. The plate E, upon which the fuel rests, is raised above the lower end of the outlet draft-flue G, and is inclined downward toward and below the lower end of the inlet draft-flue 1),which tends to keep the fuel before the draft; and, as the heater is generally emptied every time, the ashes never accumulate to obstruct it. At the upper edge of the plate E is an upward-projecting flange, d, to prevent the fuel from falling down below, and this flange is perforated to admit of the passage of the smoke through it.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, 1s

HORACE A. MEARS.
